As described above, the Status Applications provide systems andprocesses for determining the status of a variety of devices via anetwork. The importance of device status cannot be overstated. Forexample, dwelling and vehicle security is a multi-billion dollarindustry. The FBI reports a burglary occurs every 15.4 seconds. It hasalso been reported that a home without a security system is 2 to 3 timesmore likely to be burglarized.

Dwelling alarm systems typically comprise sensors, annunciators, andtelecom paths. Sensors include those for fire, motion within a room,structural movement (e.g., doors and windows), sound (e.g., glassbreaking), and panic buttons (e.g., medical or threat emergencies).Annunciators, which are activated when a sensor is triggered, includelocal audible alarms (e.g., sirens, bells, voice warnings) and messagessent using the telecom paths to an alarm call center (a central stationwhere operators monitor alarms from alarm service subscribers) ordirectly to an alarm authority (e.g., police, fire department,ambulance). Video and audio data may also be captured and transmitted.

Typically, a local sensor in a multi-sensor alarm system detects fire,motion within a room, structural movement, specific sounds, operation ofa panic buttons, or other state for which a sensor is designed (eachsuch detection is an “alarm trigger”) and sends a signal to a localprocessor (“sensor hub”), usually on premises. The sensor hub then sendsa signal over a wireline (e.g., dial-up or leased telephone line, DSL,cable modem) or wireless (e.g., mobile phone network, private radioservice) to an alarm call center or alarm authority, where a response tothe alarm is undertaken.

There are several problems with typical alarm systems. Basic dwellingalarm systems typically do not differentiate between types of alarms(e.g., fire, motion, medical). This lack of differentiation requires thealarm call center to interpret the alarms received. Errors can be madein this interpretation, and the wrong type of alarm response dispatched.Improved home alarm systems, such as that disclosed in U.S. Pat. No.6,215,404, granted to Morales, include a means of analyzing the localannunciator sound output (e.g., siren, bell), in essence, performing anelectronic interpretation of the type of alarm.

While the emphasis on alarm systems has been to improve the reporting ofan alarm condition to an alarm authority, the owner of the dwelling orvehicle that is subject to monitoring is not able to independentlymonitor alarm sensors.

Individuals not only have an interest in the status of alarm sensors butin the status of other devices as well. By way of illustration, ahomeowner may wish to monitor the status of a heating/cooling system, arefrigerator, a hot water heater, water pipes, a swimming pool, acomputer, and other systems and devices. Of particular utility is theability to monitor such systems and devices remotely and to issuecontrol commands to controllable devices. For example, a non-residenthomeowner could monitor the temperature of a vacation home and determinewhether to instruct a thermostat to increase or decrease the insidetemperature.

Communications devices also have states that can be monitored and usedto make decisions. A typical telephone status comprises an “on-hook”state and an “off-hook” state. Digital communications devices may haveadditional states that may be important in making decisions. Forexample, and not as a limitation, real time knowledge of the state of acommunications device can be used to determine when to place a call to aparty, what communication device to call, where to forward a call,whether a communications device and/or a user are present on a network,and to automatically call a party when a telephone changes from anoff-hook state to an on-hook state.

What is desired is a system whereby the status of a monitored device canbe determined remotely and decisions can be made based on the status.The desired system would allow decisions to be made by a user or to bemade automatically by another device responsive to the status of themonitored device. Additionally, a desired system would allow themonitored device to be controlled remotely based on the monitored devicestatus.

DETAILED DESCRIPTION

An embodiment of the present invention provides a system for monitoringthe status of a device and saving device status information in devicestatus file that is accessible over a network.

FIG. 1 illustrates the basic architecture of an equipment status monitoraccording to an embodiment of the present invention. Referring to FIG.1, a status accessing device 100 accesses a device status file 110 vianetwork 115. In an embodiment of the present invention, the statusaccessing device 100 is a computer, although this is not meant as alimitation. Status accessing device 100 may be any device capable ofcommunicating with device status file 110 over network 115. By way ofillustration and not as a limitation, status accessing device 100 may bea general purpose computer, a laptop computer, a personal digitalassistant (PDA), a telephone, or a cell phone. By way of illustrationand not as a limitation, network 115 may be the public switchedtelephone network (PSTN), a packet switched network, the Internet, awireless network, or a cell phone network. Device status file 110 iscontinually updated by a device status monitor 120 that constantlymonitors a series of monitored devices 130, 135, and 140.

It should be noted that it is anticipated that many thousands of deviceswill be monitored in this fashion. Eventually it is anticipated thatmillions of device will be so monitored. The monitoring function can beaccomplished by special equipment for that purpose or is simply theoutput of monitored device designed to report to a status monitor 120.

The device status file 110 is continually updated by device statusmonitor 120 with status information indicative of the status of amonitored device (130-140). By way of illustration and not as alimitation, in an embodiment of the present invention, monitored device130 is a telephone and the status information comprises its on-hook oroff-hook status. In this embodiment, a calling party communicating withstatus accessing device 100 can receive “real time” status (asdetermined by the sampling rate of device status monitor 120) ofmonitored device (telephone) 130 being called by simply monitoring theequipment status file that is accessible over network 115. Since thestatus file is anticipated to contain many thousands of numbers it isanticipated as part of the present invention that when a calling partyusing status accessing device 100 requests the status of a particulartelephone that only the status of that telephone will be returned to theuser. Alternatively, a user of status accessing device 100 may create alist of numbers to monitor and have the data “pushed” over network 115to the status accessing device 100.

In yet another embodiment of the present invention, monitored device 130comprises a security-sensing device. In this embodiment, the statusinformation gathered by device status monitor 120 is associated with ameasure of security that is sensed by the security sensing device. Byway of illustration and not as a limitation, in an embodiment of thepresent invention, a security-sensing device may be a motion detector,an audio detector, and an intrusion detector. The status informationassociated with a motion detector is movement, the status informationassociated with the audio detector is a change in sound levels over anambient sound level and the status information associated with anintrusion detector is the opening of a closed access means, such as adoor or a window.

Dwelling alarm systems typically comprise sensors, annunciators, andtelecom paths. Sensors include those for fire, motion within a room,structural movement (e.g., doors and windows), sound (e.g., glassbreaking), and panic buttons (e.g., medical or threat emergencies).Annunciators, which are activated when a sensor is triggered, includelocal audible alarms (e.g., sirens, bells, voice warnings) and messagessent using the telecom paths to an alarm call center (a central stationwhere operators monitor alarms from alarm service subscribers) ordirectly to an alarm authority (e.g., police, fire department,ambulance). Video and audio data may also be captured and transmitted.Typically, a local sensor in a multi-sensor alarm system detects fire,motion within a room, structural movement, specific sounds, operation ofa panic buttons, or other state for which a sensor is designed (eachsuch detection is an “alarm trigger”) and sends a signal to a localprocessor (“sensor hub”), usually on premises. The sensor hub then sendsa signal over a wireline (e.g., dial-up or leased telephone line, DSL,cable modem) or wireless (e.g., mobile phone network, private radioservice) to an alarm call center or alarm authority, where a response tothe alarm is undertaken.

In another embodiment of the present invention, monitored device 130 isa computer. In this embodiment, the status information gathered bydevice status monitor 120 is associated with measures of performance andcurrent state of the monitored device (computer) 130. By way ofillustration and not as a limitation, status information associated withthe computer is its presence on line, its memory usage, its temperature,processes that are running, processes that have been completed, and anydetected failures of hardware or software.

FIG. 2 illustrates an equipment status monitor according to an alternateembodiment of the present invention. Referring to FIG. 2, astatus-accessing device 200 accesses a telephone status file 210 and adevice status file 215 via network 205. In an embodiment of the presentinvention, the status-accessing device 200 is a computer, although thisis not meant as a limitation. Status accessing device 200 may be anydevice capable of communicating with telephone status file 210 and/ordevice status file 215 over network 205. By way of illustration and notas a limitation, status-accessing device 200 may be a general purposecomputer, a laptop computer, a personal digital assistant (PDA), atelephone, or a cell phone. By way of illustration and not as alimitation, network 205 may be the public switched telephone network(PSTN), a packet switched network, the Internet, a wireless network, ora cell phone network.

As illustrated in FIG. 2, telephone status file 210 is logicallydistinct from device status file 215. In this embodiment of the presentinvention, the status of telephone 250 is monitored by subscriber cableinterface device 220 and reported to softswitch 240.

In an embodiment of the present invention, telephone 250 may be adigital telephone adapted for communicating over a packet network, adigital telephone adapted for communicating over a VoIP system, a POTstelephone, a wireless telephone, or other communications device.

In an embodiment of the present invention, subscriber cable interfacedevice 225 comprises a set top box. However, this is not meant as alimitation. As disclosed in application Ser. No. 08/963,373, theconnection of the cable system can also be through any other voice/datainterface provided by the cable carrier since set top boxes will not bethe only interface to voice and data services over cable. By way ofillustration and not as a limitation, subscriber interface device 225may be a DOCSIS-compliant cable modem (CM) connected to an externalmedia terminal adapter (MTA). In another embodiment of the presentinvention, the subscriber cable interface 225 comprises an integrated CMand MTA. In yet another embodiment of the present invention, thesubscriber cable interface 225 comprises a set top box that is adaptedto receive communications over the cable network (that is, downstream)and to send communications over the cable network (that is, upstream) oranother network, such as the PSTN, a wireless network, or the Internet.

Device status monitor 255 determines the status of monitored devices 260and 265. Telephone status file 210 is continually updated by softswitch240 and device status file 215 is continually updated by device statusmonitor 255. However, this is not meant as a limitation. In anotherembodiment of the present invention, monitored device 260 is a telephonethat and the status information is provided to device status monitor255. In this embodiment, the status of monitored device (telephone) 260is reported to device status file 210.

Both device status monitor 255 and subscriber cable interface device 220are adapted to send status information as packets over cable network 230to CMTS 235. CMTS 235 routes the status file information packets toeither softswitch 240 or device status file 215, as appropriate.

FIG. 3 illustrates a call camp-on feature according to an embodiment ofthe present invention. In this embodiment, telephone A 300 desires tocall telephone B 310 via network 305. Telephony/data interface 320monitors the status of telephone B 310 and sends telephone statusinformation to telephone B status file 325. In this embodiment,telephone status information comprises an on-hook and an off-hook stateof telephone B 310. Telephone B status file 325 is accessible to astatus accessing device 335 via network 330. Telephone B statusinformation is also sent to camp-on processor 340.

Telephone A 300 initiates a call to telephone B 310 through camp-onprocessor 340. Camp-on processor 340 determines the status of telephoneB 310 by polling status accessing device 335. If the status of telephoneB 310 is on-hook, the call is placed by camp-on processor 340 andswitched to telephone A 300. If the status of telephone B 310 isoff-hook, camp-on processor 340 monitors status accessing device todetermine when telephone B 310 transitions to an on-hook state, thenplaces a call to telephone B 310. The call is transferred to telephone A300.

In an embodiment of the present invention, network 305 is the publicswitched network. However, this is not meant as a limitation. Network305 may be any network on which telephone calls may be placed. By way ofillustration and not as a limitation, network 305 may be the Internetand the communications between telephone A 300 and telephone B 310 maybe VoIP calls.

As will be appreciated by those skilled in the art, while network 305 isillustrated as a single network, the path between telephone A 300 andtelephone B 305 may comprise a number of networks using varioustransport means and signaling protocols. By way of illustration and notas a limitation, a call originating from telephone A 300 may be a VoIPcall placed over a cable network that is routed to telephone B 310 viathe PSTN. One such protocol is the session initiation protocol (SIP).

In an embodiment of the present invention, network 330 may be the publicswitched telephone network (PSTN), a packet switched network, theInternet, a wireless network, or a cell phone network.

In another embodiment of the present invention, the status of a deviceis presented and a user of a status accessing device is provided theability to control the device remotely.

FIG. 4 illustrates a flow of a process by which a status of a thermalcontrol device is obtained and a control option is presented accordingto an embodiment of the present invention.

Referring to FIG. 4, a device status file of a controllable devicereceives device status information 400. The device status information isaccessed 405 and the option to issue a control command is presented 410.If the option to issue a control command is not exercised, the devicestatus is monitored 415 and process repeats 400. If the option to issuea control is exercised, the control command is selected 420 and theselected command is sent to the controllable device 425. The devicestatus is monitored and the status information is updated to reflect theissuance of the control command 430 and the process repeats 400. By wayof illustration and not as a limitation, in an embodiment of the presentinvention, the controllable device is a thermostat and the controlcommand is selected from raise temperature and lower temperature. Inanother embodiment of the present invention, the controllable device isa security monitoring device and the control command is directed to thesecurity monitoring device. By way of illustration and not as alimitation, the security monitoring device is a video camera and thecontrol command is selected from the group consisting of pan up, pandown, pan left, pan right, zoom in, and zoom out.

Referring to FIG. 5, an alternative embodiment of the present inventionis illustrated. While it is important for callers to be able toascertain whether the party is online or not, this is also particularlyimportant when one is dealing with wireless communications. For example,and as described earlier, status accessing device 500 access network 502to ascertain the status of wireless telephones 512, 514, and 518. Thequery concerning the equipment status then proceeds through a wirelessapplication protocol (WAP) interface 506 to wireless network 508. Therequest then flows to the wireless network manager 510 which recordswhich wireless phones are currently available on the network and whichof those telephones is engaged in an active telephone call. Thus networkmanager 510 “knows” that wireless telephones 512 and 514 are availablefor telephone calls or in the alternative that, for example, wirelesstelephone 514 is engaged in an active phone call. This information isthen sent by network manager 510 over wireless network 508 through WAPinterface 506 through network 502 to status access device 500. At thatpoint the user of status accessing device 500 can decide to make atelephone call using telephone 532 and network 504 through the WAPinterface 506 over wireless network 508 to the wireless telephones 112,114. In an embodiment of the present invention, telephone 532 is aconventional telephone and network 504 is the PSTN. In anotherembodiment of the present invention, telephone 532 is adapted to use theVoIP and network 504 is an IP network.

Knowledge of the status of telephones is particularly important wheretelecommunications service providers (TSPs) utilize business modelsbased on charging the caller for calls made over the TSP's facilities.The PSTN uses this model as do providers of VoIP services. Wirelessproviders may also shift to this model. Thus, in a situation where acaller is charged for all telephone calls made, it will be particularlyimportant to the caller that it not get charged for leaving a messageover a wireless network which tends to be particularly expensive.

The expense in dealing with a wireless network is all the more apparentwhen one considers that a telephone may be in a “roaming” mode where thetelephone is in a network that is not the home network for the wirelesstelephone. Thus, in the case where wireless telephone 518 is roaming ina second wireless network 516, a telephone call that is not completed orwherein a message is simply left, becomes all the more expensive sinceroaming charges will be charged to the caller as well.

FIG. 6 illustrates the logical elements of a status monitoring systemutilizing an RFID tag according to embodiments of the present invention.Referring to FIG. 6, a device monitor 805 monitors the status ofreceiving devices RD “A” 820 and RD “B” 825. RD “A” 820 and RD “B” 825each comprise an unique address. Device monitor 805 creates status file“A” 850 comprising the status of RD “A” 820 and status file “B” 855comprising the status of RD “B” 825. These status files are availableover network 860 sending devices 830 and 835. Sending devices 830 and835 select a receiving device (RD “A” 820 and/or RD “B” 825) tocommunicate with using the address of the selected receiving device.Communications are established via network 865.

In an embodiment of the present invention, receiving devices RD “A” 820and RD “B” 825 are telephones and the addresses are telephone numbers.As previously described, the status of a telephone receiving devicecomprises the “on-hook” or “off-hook” state of the receiving device andother information about the state of the device that would be useful toa sending device. By way of illustration and not as a limitation, thestatus may include whether the device is forwarded, the number of ringsbefore the device is answered by an automated answering device, andsimilar state information.

As will be appreciated by those skilled in the art, communications maybe established between other sending devices and receiving deviceswithout departing from the scope of the present invention. By way ofillustration and not as a limitation, receiving devices and sendingdevices may be a computing device, a digital telephone providing voiceover IP, a personal data assistance, a cell phone, a radio phone, avideo phone, and the like. Additionally, sending devices may beswitches, routers, proxy servers and other devices that brokercommunications between receiving devices and other sending devices.

The status of a receiving device is directly related to the media thereceiving device uses for communication, the type of communications thereceiving device receives, and the functionality that is embodied in thereceiving device. By way of illustration, if the receiving device is anIP networked device, the status comprises the IP address of thereceiving device, port information, firewall information, and networkaddress translation information.

Networks 860 and 865 may be wired, wireless, fiber, hybrid fiber coax,switched, packet-based, and combinations of the same. Additionally,networks 860 and 865 may be the same or different media. In an exemplaryembodiment, network 860 is the Internet. In another exemplaryembodiment, network 865 is a telephone network.

In an exemplary embodiment of the present invention, the status of areceiving device further comprises a recipient list of users able to usethe receiving device at any particular time. In this exemplaryembodiment, the recipient list is created by the receiving device inresponse to the detection of a qualified user within a preset accessdistance of the receiving device. A sending device may access thisstatus information and determine how to communicate with a user on therecipient list.

Referring again to FIG. 6, device monitor 805 further comprises an RFIDmonitor 848 that may communicate with RFID tag “A” 840 and RFID tag “B”844. In the embodiment illustrated in FIG. 6, RFID tags 840 and 844 arepassive devices. However, the present invention is not so limited.Semi-passive or active RFID tags may be utilized without departing fromthe scope of the present invention. Additionally, RFID tags 840 and 844comprise memory (not illustrated) in which RFID identifier “A” 842 andRFID identifier “B” 846 are stored. The memory may be either a read onlymemory or programmable read/write memory.

RFID monitor 848 polls RFID tag “A” 840 and RFID tag “B” 844. An RFIDtag within a preset distance of RFID monitor 848 will respond with areflected signal comprising an RFID identifier of the responding tag. IfRFID tag “A” 840 responds to the poll from RFID monitor 848, RFIDmonitor 848 will receive RFID identifier “A” 842. If RFID tag “B” 844responds to the poll from RFID monitor 848, RFID monitor 848 willreceive RFID identifier “B” 846. If both tags respond to the poll, RFIDmonitor 848 will received both RFID identifier “A” 842 and RFIDidentifier “B” 846. The RFID identifiers are then added to theappropriate receiving device status file.

Both sending devices 830 and 835 have access to the receiving devicestatus files (850 and 855) and to datastore 810. Datastore 810 maps anRFID identifier in a receiving device status file to an addressassociated with a user and to an address of the receiving deviceassociated with the receiving device status file. Thus, a sending device“knows” at a point in time (determined by the polling rate of RFIDmonitor 848) that a user is within a preset proximity to a receivingdevice. A communication directed to that user's address may then bedirected to the address of that receiving device.

In an alternate embodiment of the present invention, access to thestatus information of a receiving device is limited to a sending deviceor a sender that has been pre-qualified to access that statusinformation. The identity of the sending device or caller is establishedusing the address of the sending device or an identifier of the sender.By way of illustration and not as a limitation, a sending device may beidentified by its network address or MAC address and a sender may beidentified by his or her telephone number, e-mail address, or SIPaddress. In yet another embodiment of the present invention, the sendermay be prompted for a user ID.

As will be appreciated by those skilled in the art, the statusmonitoring system illustrated in FIG. 6 and described above may be usedin many applications. By way of illustration and not as a limitation, inan embodiment of the present invention, a status monitoring systemmonitors a telephone system. In this embodiment, the telephone systemmay be operated within an office, a hotel, a hospital, a home, anairport, and similar environments. The system may comprise a singlelocation or multiple locations.

In this embodiment, a sending device (830) is a switching device thatreceives a call from a calling party directed to a called party usingthe called party's telephone number. The called party is assigned to RD“A” 820 and RFID tag “A” 840. Sending device 830 checks status file “A”850 and determines that the called party is not in proximity to the RD“A” 820. Sending device 830 then checks the status files of all otherreceiving devices on the network to determine whether the called partyis in proximity to any other receiving device. In this example, ID “A”842 associated with RFID tag “A” 840 assigned to the called party islocated in status file “B” 855 indicating that the called party is inproximity to RD “B” 825. Send device 830 redirects the call to RD “B”825 and the parties are connected.

FIG. 7 illustrates the components of an RFID monitor according to anembodiment of the present invention.

Referring to FIG. 7, an RFID monitor 900 comprises a signal acquisitionelement 910, a signal processor 920, an object identification manager940, a separation manager 960, an RFID status report generator 990, andan RFID tag query manager 905.

RFID query manager 905 sends a query signal during a preset time period.In another embodiment of the present invention, the power of the querysignal sent by query manager 905 may be adjusted. The query signal isreceived by an RFID tag 980 and reflected back to alert module 900. Thereflected signal comprises the code 982 stored in memory 984. Signalacquisition element 910 receives the reflected signal emitted by RFIDtag 980. The signal acquisition element 910 comprises a device ordevices appropriated to receive the signal generated by RFID tag 980. Inan embodiment of the present invention, the sensitivity of the signalacquisition element 910 may be adjusted. The reflected signal from thesignal acquisition element 910 is received and processed by signalprocessor 920. The processed signal is sent from signal processor 920 toan object identification manager 940 to obtain the RFID tag code 984.The signal is also provided to separation manager 960 to determine ifthe distance between the RFID monitor 900 and the RFID tag 980 exceeds apreset separation distance.

If the preset separation distance is not exceeded, the separationmanager 960 sends “present” signal to RFID status report generator 990indicative of the proximity of RFID tag 980 to the receiving devicebeing monitored. RFID status report generator 990 will send a statusreport to the status file (see FIG. 6, 850 or 855) of the receivingdevice being monitored reporting the proximity of RFID tag 980 with RFIDtag code 984 in proximity to that receiving device.

If the preset separation distance is exceeded, the separation manager960 will take no action. In this case, RFID status report generator 990will not receive a “present” signal. If RFID report generator 990 haspreviously received a “present” signal relating to RFID tag 980, thenRFID status report generator 990 will send a new RFID status to theappropriate status file removing RFID tag 980 with RFID code 984 fromthe list of RFID tags in proximity to the receiving device beingmonitored. In an embodiment of the present invention, RFID status reportgenerator 990 waits a number of polling cycles in which the presetseparation distance between RFID monitor 900 and RFID tag 980 isdetermined to have been exceed before removing RFID tag 980 from thelist of RFID tags in proximity to the receiving device being monitored.

In one embodiment of the present invention, separation manager 960determines that the preset separation distance has been exceeded basedon a lack of a reflected signal from RFID tag 980.

In another embodiment, separation manager 960 uses the signal strengthof the reflected signal to determine that the preset separation distancehas been exceeded. In conjunction with the variable power of the querysignal emitted by query manager 905 and the variable sensitivity of thesignal acquisition element 910, the separation distance threshold may beadjusted. As will be appreciated by those skilled in the art, that othermeans may be used to determine that the preset separation distance hasbeen exceeded without departing from the scope of the present invention.

The monitoring system and method of the present invention alsocontributes to the changing environment of office “hoteling” whereinmultiple workers, each of whom may telecommute, may use the same officewhen they are present at different times in the physical location oftheir organization. In this manner, a worker can check into the officeto be used and, via the present invention, have calls routed to thatoffice and have appropriate computer access to files based on the statusof the receiving device in that office (i.e telephone, computer, faxmachine, PDA, cell Phone). As a user's profile status changes,regardless of where the worker resides in a vacant or temporarilyassigned office, the permissions for file access and telephone routingwill be enabled and be appropriate to the permission level of thatworker.

Referring now to FIG. 8 an alternative embodiment of the status filechecking of the present invention is illustrated in the context of ahotel environment. This description is not meant as a limitation sincethe status files checking and permissions as described below are equallyapplicable in a variety of settings. By way of illustration and not as alimitation, the description that follows may be applied to a hotel, ahospital, a cruise ship, a movie theater, an educational institution, anemployment center, a detainment facility, a military facility, a policefacility, a governmental office, and a research facility.

In this illustrative embodiment of FIG. 8 a guest is issued an RFID“key” 1002 upon check in. At that point registration informationconcerning the guest is stored via a registration/status server 1000into an ID store 1016. Part of that information is the identity of theguest, the charge card/debit card being used and other informationcustomary in the trade. However, in addition, the guest can specify whatother services are desired such as refrigerator access, phone access,video access, internet access and other services that a hotel mightoffer on a “pay-as-you-go” basis. Any such service elections are alsostored in the ID store 1016 along with the RFID Key 1002 identity. Inthis way, the guest receives permissions to use any number of controlleddevices, for example and without limitation, a telephone, arefrigerator, an entertainment center, and a computing device.

Thereafter, the guest may be admitted to the room via use of the RFIDKey 1002 and the room authorization device 1004 such as, and withoutlimitation, and RFID activated door lock. When the guest desires to usethe smart telephone 1006, the RFID key 1002 is simply brought intoproximity of the telephone, which comprises an authorization devicehaving RFID checking capability (not illustrated) and a signal is sentvia network 1014 to registration/status server 1000. Registration/statusserver 1000 checks the ID store 1016 to determine if smart telephone usepermission has been granted. If so, the smart telephone 1006 isimmediately available for use by the guest. In this instance differentlevels of access may be granted to a specific key holder. For example,one key holder may have full access to controlled devices that providelocal, long distance, international and a variety of other callingservices. Another guest, for example a minor having his/her own key, maysimply have access to a telephone to make limited local calls.Similarly, access to videos and other entertainment media havingdifferent ratings can be controlled based on the RFID key 1002 issued toa guest.

If the guest desires access to the in-room refrigerator 1008, thatdevice also comprises an authorization device having RFID checkingcapability (not illustrated). The guest again use room key 1002 toobtain access to the refrigerator 1008. Access is then granted once theRFID key ID is checked over network 1014 via registration/status server1000 and ID store 1016.

Access to the Internet 1010 and in room games and videos 1012 is alsocontrolled based upon permission given to specific key holders. All keyholders are separately identified in ID store 1016 in association withtheir respective permissions.

In an alternative embodiment, when a guest checks in and uses key 1002to enter a room via room authorization device 1004, theregistration/status server 1000 and ID store 1016 are notified that theroom was access by the appropriate guest having a particular RFID key1002. Thereafter, upon checking of the permissions for that guest storedin ID store 1016, signals are sent to the various in-room controlleddevices (smart phone 1006, refrigerator 1008, web access 1010, and videoaccess 1012) that the guest requested permission to access on check in.When the guest leaves the room, and when the RFID comes in the vicinityof the room authorization device 1004, all in-room facility access isturned off until that guest returns.

Using the present invention, other keys may be issued to other staffpersonnel depending on the level of access desired. For example, themaid service may require access but are not permitted access tointernet, telephone refrigerator or other services. However, uponentering a room, the registration/status server 1000 is sent a messagethat a certain key holder (staff member) is present in the room. Withthat information, management can contact the staff worker via the smartphone 1006 should the need arise. However, the staff member would notnecessarily have access to other in-room facilities. Any such accesswould be denied by the registration/status server 1000.

In still another embodiment of the present invention, when a callerdesires to reach a guest, the operator in the hotel can access thestatus file of the telephone in the guest's room to determine if theguest is present or on the line. The caller can then either be informedof that device status or be put through to the room if the guest ispresent on not on the telephone.

It should be noted that, while a single network 1014 is noted in FIG. 8,this is not meant as a limitation. Access signals and permissions may betransmitted to the registration/status server 1000 over multiplenetworks such as wired and wireless networks, depending upon theconfiguration of the communication system in the hotel (or otherfacility). In addition, other signals relating to the status of in-roomfacilities are also available over the network of the present invention.Such things as refrigerator temperature may be sent independent of anyaccess request in order to track where the refrigerator 1008 isoperating. The status of the internet access device (router, hub etc)can also be verified while the guest is away via signal over thenetwork. Similarly the set top box, cable modem, may be checked over thenetwork to ensure all is in working order.

This illustration is not meant as a limitation. For example, statuschecking using RFID storage and access of the present invention canequally be used in a factory settling where access and status of devicesand personnel must be controlled. Hospitals will also benefit from thestatus checking of the present invention as well. Many other facilitiessuch as schools, movie theaters, research laboratories, military andpolice facility, and correctional institutions will also find utility inthe present invention where status of devices, and identification ofusers is desired in order to regulate access to controlled devices andspaces.

For example, in a movie theater embodiment, movie theatre ticketscomprise an RFID tag. Permissions are associated with specific tags sothat a “PG” movie will have and RFID tag identifying the ticket as onethat admits a person only to that level of movie. Attempts to by aticket holder to enter a movie with a more restrictive rating will bethwarted by alarm, door entry restrictions and the like. Similarly, aticket for an “R” rated movie will have an appropriate RFID tag ticketthat will allow entry to that movie. The RFID tag tickets of the presentinvention also allow attendance figures to be taken, allow specificmovie times of attendance to be policed and allow other functionsrelating to movie attendance (concessions, leaving early etc.) to betracked.
